Abstract:
An apparatus for swiveling an implement, such as a bucket, relative to a device, such as an excavator boom, includes a rotary union and a bearing disc mounted in a housing. The bearing disc rotates relative to the housing so that the implement can be rotated relative to the device. A gear or geared bearing assembly is located between the bearing disc and top and bottom housing portions for bearing loads transverse to the axis about which the implement is rotated relative to the device. The rotary union has fluid passages extending from the top to the bottom of a central shaft, which is affixed to the bearing disc, and the shaft and disc can comprise a one piece combination rotary union and bearing disc.
